So, the fuel quantity indicators tank indicators (ie the gauges) are completely driven by the in-tank sensors. The fuel computer totalizer is completely independent from that, and is driven by the initial fuel state that you provide, minus the fuel that flows through the flow sensor. I guess the first question here is - which value is fluctuating? Can you post a picture?

Total fuel or remaining fuel fluctuating only

I assume since you press a button after getting gas that you are referencing the computer fuel remaining versus the fuel levels.
what are you using? red cube? For your fuel flow.
have you calibrated it ( this first time using ) or
did it work and now it is not? - if you have a red cube and it worked before? if so, It may have to do with something being stuck is turbine Causing issues. Take the fuel computer out and attempt to clean it. If it’s new it’s covered under warranty.
